BELT INSTALLATION
EXPLANATION:
The Belts used in your Crawler
are special. Do not confuse them with inexpen-
sive, fractional horsepower consumer Belts.
Your Crawler Belts are made for difficult, high
horsepower, shock load, industrial applications.
Formulated with industrial grade rubber com-
pounds, they feature a Kevlar (bulletproof plastic)
cabled core. Molded around each Belt is a special
fabric jacket that forms the Belt’s “clutch face”.
In an hour or so of operation this fabric jacket
gains a smooth “glaze” and forms the clutch face
necessary for smooth Track Clutch engagement.
CAUTION:
NEVER, NEVER, use fractional horse-
power Belts in your Crawler. They are made with
light weight, “sticky compounds” that will not form
a proper glaze. This means you will not have the
SAFE clutch action mandatory for SAFE Crawler
control! In addition, fractional horsepower Belts
will break during shock loads and will leave your
clutch system out of control!
NOTE:
During the first hour or so of “breaking-in”
a new set of Belts, you potentially may hear a
squealing sound when turning.
Do not be
alarmed. This is characteristic of a new set of
Belts until they have become permanently
“glazed” and gain proper smooth clutch action.
Slip the Track Clutch Belts you are installing
through the “slot” you created on the “end” of the
appropriate #1627 Upper and #1643 Lower Power
Shaft. [Belts #1, #2, #5 & #6 on the Upper Power
Shaft; Belts #3 & #4 on the Lower Power Shaft].
Slide them to the center of your Crawler.
With the (above) lubrication completed, slide the
Bearing & Shells assembly on left end of each
Upper & Lower Power Shaft back into position on
the “threaded studs” protruding from crawler wall.
Replace original nuts over Bearing threaded studs
and tighten.
Take original #1807 Set Screw & #1808 Nut “as-
sembly” and thread it into its original threaded hole
of bearing...rotate the #1627 (or #1643) Shaft
within the bearing to align the end of the #1807
Set Screw with its mating “V” slot in shaft’s end.
Use your Allen Wrench to tighten the Set Screw
...make sure it’s end hits the “V” slot dead center.
With your open end wrench tighten your #1808
Jam Nut. (Use this procedure for
both
the Upper
& Lower Power Shafts). When you are done the
bearing end of shaft should look like photo above.

SPECIAL NOTE:
It’s manditory that you
keep “left ends” of the Upper & Lower Power
Shafts properly lubricated. A film of grease
must totally cover the Shaft ends from the
#2041B Pulley to the “left end” of each Shaft!
As you grease the Shaft, work the #252B
Bearing back and forth to make sure it’s com-
pletely coated! To ignore this procedure may
make it impossible to slide the Bearing to
change Belts in the future, which would re-
quire serious drive train rebuilding to correct
the problem.
